When their sprightly five- year-old daughter turned unusually quiet and reserved a month after going to a famous kindergarten, Mr Xu Xuejin and his wife decided to take matters into their own hands.
They pulled the girl, Feiya, out of the kindergarten and settled on homeschooling instead, crafting a lesson plan that suited her interests and personality.
They also gave her a say in what she wanted to learn.
"We felt that the traditional school system was unsuitable as they used a very standardised approach that might not fit the needs of some children well," said Mr Xu, 37, who runs his own trading firm in southern Guangdong province.
Religion was also a factor for Mr Xu, a Christian, who told The Sunday Times over the phone that he wanted to give both his children a more "Bible-based" education.
The teacher's role is one that he and his wife have continued to play in the past four years for Feiya, now nine, and for their second child, Xiaolang, five.
Rather than just boring textbooks, materials such as picture storybooks are used in teaching Feiya. Bible lessons are thrown in as well.
